✓ you are helping the environment (woot!) as bamboo is a renewable resource
✓ this is a one of a kind One Happy Leaf design (less likely to have those awkward moments of "oh, you are wearing the same thing I am" - Ek!), and
✓ you have supported a very lovely Australian crafter (that's me!)
Also, if you live outside of Australia there is a bonus:
✓ whenever someone compliments you on your earrings, you can say "thank you, I bought them from a boutique Australian artist"
